Description
The MCP73213 is a highly integrated Li-Ion battery
charge management controller for use in space-limited
and cost-sensitive applications. The MCP73213
provides specific charge algorithms for dual-cell Li-Ion/
Li-Polymer batteries to achieve optimal capacity and
safety in the shortest charging time possible. Along
with its small physical size, the low number of external
components makes the MCP73213 ideally suitable for
portable applications. The absolute maximum voltage,
up to 18V, allows the use of MCP73213 in harsh
environments, such as low-cost wall wart or voltage
spikes from plug/unplug.
The MCP73213 employs a constant current/constant
voltage charge algorithm. The various charging voltage
regulations provide design engineers flexibility to use in
different applications. The fast charge, constant current
value is set with one external resistor from 130 mA to
1100 mA. The MCP73213 limits the charge current
based on die temperature during high-power or high-
ambient conditions. This thermal regulation optimizes
the charge cycle time while maintaining device
reliability.
The PROG pin of the MCP73213 also serves as enable
pin. When high impedance is applied, the MCP73213
will be in Standby mode.
The MCP73213 is fully specified over the ambient
temperature range of -40°C to +85°C. The MCP73213
is available in a 10-lead DFN package.
